Variables
static constexpr double	srfm::constants::BETA_MAX_SAFE = 0.9999
static constexpr double	srfm::constants::BETA_NEWTONIAN_THRESHOLD = 0.1
	Below this β, relativistic corrections are negligible (γ ≈ 1 + β²/2).
static constexpr double	srfm::constants::FLOAT_EPSILON = 1e-12
	General floating-point comparison epsilon.
static constexpr double	srfm::constants::METRIC_SINGULARITY_EPSILON = 1e-14
	Epsilon for metric invertibility check (det(g) must exceed this).
static constexpr double	srfm::constants::MIN_VOLATILITY = 1e-8
	Minimum volatility to prevent a singular diagonal metric entry.
static constexpr double	srfm::constants::SPEED_OF_INFORMATION = 1.0
static constexpr double	srfm::constants::DEFAULT_GEODESIC_STEP = 0.01
	Default proper-time step for geodesic integration.
static constexpr double	srfm::constants::DEFAULT_FD_STEP = 1e-5
	Default finite-difference step for numerical metric derivatives.
static constexpr std::size_t	srfm::constants::MIN_RETURN_SERIES_LENGTH = 30
static constexpr double	srfm::constants::DEFAULT_RISK_FREE_RATE = 0.0
	Default annualised risk-free rate (zero — excess-return framing by default).
static constexpr double	srfm::constants::ANNUALISATION_FACTOR = 252.0
	Default annualisation factor: 252 trading days per year.
